All grounds were good to the firewall, more I think about it the ecu is probably the issue. Just a strange one because it really is intermittent.

I’ve had it happen before with the ECU, one minute fine...the next no start or rough running...then fine again.

When they get wonky like that it’s mostly related to temperature. Did you guys move the car indoors and warm it up?
